For each cassette that I delivered - each one the only copy of a day of my furtive performance, and each one abandoned in the mailbox of an unknown viewer - I made a drawing of the exterior box.

These drawings replicate the commercial box in which the cassette was sold. In total, there are twelve boxes. They each differ subtly, and act as evidence of the performance, the delivery, and my physical inability to replicate as identically as a machine.
